PAR2 Multithreaded Archive Recovery Performance
Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive
Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
An application needs to be more than multithreaded to take advantage of the 980X, it needs to demand more than four threads. And our PAR2 test is pushing it as is, there's no advantage to the 980X here.
WinRAR - Archive Creation
Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:
Our WinRAR test takes advantage of the larger L3 cache and thus we see roughly a 9% performance advantage for the 980X compared to the 975.
Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
If you're running any sort of computationally intensive Excel macros, the 980X will deliver. The financial market just wet themselves.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
Even when the application doesn't scale perfectly with core count, we still see some impressive gains. Our MPEG-2 Blu-ray creation test showed a hefty 20% performance improvement over the 975. If you do any sort of video encoding or Blu-ray authoring, the 980X is perfect for you.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
FLV authoring shows another healthy gain of 30% over the quad-core 975.

I would love to see a task manager screenshot during the different multi-threaded benchmarks, also games, so we can see how it utilizes the six cores and two threads per core?drewintheav - Tuesday, March 16, 2010 - link
The INTEL i7 980X has dual QPI's and will run in a dual socket mainboard!!!Such as the EVGA W555 / Classified SR-2

Where did you get that information from? On intel website it says 1 QPI. from what I know and what always was the case all i7 series are single QPI's.THats why you have Xeon series with double QPI.
Please do not post incorrect information, because people get stuck with expensive equipment not able to use it properly.

This has got to be THE most worthless, useless, expensive pice of silicon I've ever seen. An average of 13% performance increase in SOME apps AND a decrease in gaming?Give me that 1k, and I'll get myself a GTX480, an SSD, and some DDR3 modules that will give me 2x, 3x or Xx times more performance in EVERYDAY use.
Thank goodness for CUDA, Stream, OpenCL and all that cr4p.

Aenslead,I think you're missing the whole point of this cpu. It wasn't built to go fast. It was built to due serious multi-tasking. The pro A/V crowd will buy these in droves.
I can't wait to get one for my digital audio system. It will be worth every penny.

I understand your point.I do video editing myself as well as some animation, but thanks to Furry Ball (Maya) and Elemental plugins for AE and Premiere, I've come to love GPU power more than ever.
I've seen what's comming for CS5 and I do not see CPU playing an important role there.
I see very few people, like yourself, actually finding bennefit from these product launches - same goes to PII X6, although I believe this one will be FAR better priced and far more atractive.
Best,

Wondering how the i7 980X would do against a 6 core Opteron,Tech Report did some benchmark numbers when the 6 core Opterons (server) first came out,going head to head againt Xeons..interesting results when you compare the new i7. This is a rough estimate, but if AMD's 6 core is based on the 6 core Opteron this could be interesting..

I'm somewhat confused as to why, on your review, the PII X4 965 seems rather greedy, but on Toms' review of the i7-980X, AMD's offering does much better.Toms' test setups for the X58:
Gigabyte X58A-UD5 (LGA 1366) X58 Express, BIOS F4
Corsair 6GB (3 x 2GB) DDR3-1600 7-7-7-20 @ DDR3-1333
Yours:
Intel DX58SO (Intel X58)
I'm going to presume Corsair DDR3-1333 4 x 1GB (7-7-7-20)
Toms' test setup for AM3:
Asus M4A79T Deluxe (Socket AM3) 790FX/SB750, BIOS 2304
Corsair 4GB (2 x 2GB) DDR3-1600 7-7-7-20 @ DDR3-1333
Yours:
Gigabyte GA-MA790FX-UD5P (AMD 790FX)
I'm going to presume Corsair DDR3-1333 2 x 2GB (7-7-7-20)
Toms' has the PII X4 965 idling 21W lower than the 980X and 32W lower at load (using Prime95), however you have the 965 idling 10W HIGHER and using 4W more at load. Is Prime95 just favouring AMD or is there some sort of problem with your 790 rig? I will concede that the AMD rig will be using less RAM on the Toms' setup which may account for some of the difference.
One thing to note: up the resolution on a CPU-limited title such as Left4Dead and the performance gap narrows markedly. Enable AA and there's no difference at all. For graphically intensive games and/or highest settings, it won't make sense to fork out $1000 no matter how good the CPU.
It'd be nice to see how good this CPU is with multiple graphics cards... :)
